Properties of Metal Powders for Additive Manufacturing: A Review of the State of the Art of Metal Powder Property Testing

This report is the second in a series of reports from the National Institute of Standards and Technology’s (NIST’s) Engineering Laboratory project titled Materials Standards for Additive Manufacturing. This project provides the measurement science for the additive manufacturing (AM) industry to measure material properties in a standardized way. Currently there are few consensus-based standards in this area. This project, in conjunction with NIST’s Fundamental Measurement Science for Additive Processes project, will provide the technical foundation necessary to develop new consensus-based standards. Development of standards will be done via ASTM-International’s (hereafter referred to as ‘ASTM’) Committee F42 on Additive Manufacturing Technologies and the newly formed International Organization for Standardization (ISO) TC261 committee on Additive Manufacturing.
